Purpose and scope of Shun

Technical filling different models differs, as control points are individually functional orientation.

Manufacturers offer a ready-made standard schemes, but they do not always meet the specific requirements, so there is such a service as the production of the control unit to order. To begin, we try to consider the common ground uniting all models.

Functional responsibilities of the control cabinet

The main function of any distribution station is the organization of the work connected equipment, in this case - the pump. With one remote control (which is useful if a large distance between objects) performed effectively control motors drainage, surface, downhole pumps.

The number of connected units can be different. Minimum connection - one borehole or submersible pumpThat carries the flow of water and ensures the presence of all the water supply system (heating, sprinkler). In addition it is connected sump pump needed for pumping water for household and emergency situations.

The functional purpose of the pump control cabinets is to protect the pumping equipment and control performance by changing the frequency of the load

The characteristic technical equipment

Besides the standard automatic devices that protect electrical equipment from overload and preventing operation mode in unbalance cabinets fitted with sensors reacting to violation modes of pumps

Signal display mode disturbances

Among important for normal functioning of the sensors appear on devices that capture and signals a power failure, the water level drops below the limited boundaries maturing or the event of accidents

Management of water pumps

The most common group Shun manages all kinds of water supply pumps, providing water from a source, supplying it to the consumers, the pressure increase

Wardrobe circulation pump

Cabinet for control of circulation pumps, providing continuous motion of the coolant in the heating circuit or an increase in pressure in the water

Automatic on / off pump motors makes life easier for the owners of private homes, allowing free time to spend with your family, not for manual changeover switch.

Just a few handy features that can "instruct" automation:

  • control line voltage required for the smooth operation of the equipment;
  • protection mechanisms against power interruptions and short circuits;
  • control of the water level in the well (or other vessel) and responding to its disadvantage;
  • fixing pressure surges and adjustment of optimum parameters (engine stop when reaching a critical level, running in the alignment indicators);
  • remote control of downhole pumps, direct access is not possible;
  • distribution of load across multiple units or emergency connection fallback.

As a result, the centralized automatic control operation of pump stations It becomes more productive, and the service life of electrical equipment increases markedly. Modern electronic systems allow programming mechanisms and to include them in an easy mode (for example, only during the day).

BRIEF DESCRIPTION standard

The presence of certain elements depends on the number and category of pumps, narrower or wider technical capacity, availability of additional functions.

Pressure Control Scheme

Pressure Pump Control 3.3: functional diagram of the device. Is automatically shutdown and emergency lock when overloaded, "dry running", change the water level in the tank (+)

Basic equipment for the majority of models for sale, as follows:

  • The rectangular metal housing disposed on the front side of the control panel. panel design may differ, but there are always present and indicators of the "Start" button or "Stop".
  • Switch (one or more) that allows you to turn on / off the pump in manual mode.
  • Fuses and protection elements.
  • the control part adjusting the voltage of three phases.
  • The frequency converter is required for the control of asynchronous motor.
  • Automatic adjustment unit that is responsible for routine and emergency shutdown equipment.
  • Includes sensors showing the pressure and temperature of the water.
  • Thermal relays.
  • A set of light bulbs - light alarm.

Basic functions incorporated in the control unit depends on several factors. For example, if two pumps, main and auxiliary (backup) set program allowing alternately comprise the two mechanisms.

Control Panel

two-pump control panel operating in the backup mode of use. The advantage of incorporating interval - even load distribution and increase in scheduled resource

The temperature sensor protects the equipment from overheating and work in dry run mode (probability of occurrence of such a situation occurs frequently in wells with low flow rate). Automation equipment stops, and upon the occurrence of safe conditions for the intake of water again includes a motor connected pump.

Instruments of protection from power surges, phase loss, incorrect connection protects mechanisms and do not allow them to operate in emergency mode. They adjust network settings, and only after aligning the indicators automatically connected equipment.

Approximately the same overload protection function. For example, there is a ban on the simultaneous activation of the two pumps, which leads to unnecessary costs and inefficient use of equipment.

Manual control

Almost all established systems have the ability to change from a fully automatic control to manual. This is necessary for the maintenance, repair, replacement of worn or burnt parts

Suppose, if the faulty one pump, it can be freely removed and sent in for repair, disabling automatic and manual control using.

Additional options and features

Various manufacturers include in the basic set of additional features that extend the management capabilities. For example, the company Alta Group provides a system AVR - inclusion of backup power automatically. The need for this function due to the fact that the work of the pumping station is part of the life support system at home, therefore, the network must operate continuously.

The operating principle of the ATS following: once, stops the main power supply is automatically entered backup network. It operates to reopening of the primary source.

When activated, the system checks intelligent optimal parameters, and only when a positive response once again connects the main network. If the test analysis is unsatisfactory, the system will continue to work from a backup source.

Low temperatures and high humidity - the enemies of electronic filling cabinet, so manufacturers offer service to additional warming. It is relevant for the northern regions and for all sectors, if the equipment is on the street.

Thermal insulation Shun

The so-called "hot pack" - a layer of insulation, padded on the inside. Insulated ShUNy operated at a sufficiently wide temperature range - from -40 to +55 ° C

Fairly widespread addition, to protect the engine pumps overload - softstarter. It is to trim gradually rising voltage supply mode, whereby the motor is prevented from sudden start is inputted to the work slowly and carefully.

Modern scheduling feature allows you to manage pumping stations on distance. remote warning systems are constantly connected to the GPRS, wireless modem or the Internet, so that in an emergency situation immediately activated locking system, and the signal is transmitted to the receiving device (telephone or laptop).

Convenient option that lets you specify a particular program, it is possible through the use of the controller. He is automatically able to independently affect the operation of the pumps, connect additional devices to optimize the functioning of the system as a whole.

Indication on the external panel

Display means located on the cover of the cabinet of the electronic display with a voltage and current readings and statistics: the number of starts, engine operating hours, the volume of water

Another successful option to get information about the system stop or emergency situation, - installation of lights and sirens. Upon the occurrence of force majeure beacon lights shining light and a special sound device gives a loud signal repeated.

Samples of the electron-technical connection schemes

equipment assembly occurs in the production environment, the same concepts are made pump control cabinet. The simplest is a single pump wiring diagram, although a set of additional devices can complicate installation.

As a sample take-Shun 0.18-15 (Frontier Company) designed for manual and automatic electric pump station control. The control circuit is as follows:

The operating principle of Shun in the automatic mode: the critical lowering of the water level in the water wells and actuation of the float №1 stopped operation of all pumps. In the normal liquid level condition is triggered float №2 and runs one of the pumps. When triggered, the other floats are at higher levels, introduce other units.

Features installation of monitoring stations

Without exception, Shun performance are complex devices operating from the mains, which means that install, commission, maintain and repair the equipment must be in accordance with the instructions manufacturer. The rules contained in the instructions of different models, can differ, since design tools and technical characteristics are also different.

  • The electrical connection must be carried out by a person having special authorization.
  • Shun parameters must match the settings of all connected equipment.
  • Installation is carried out in accordance with the circuit diagrams contained in the annex to the manual.
  • cable cross-section must correspond to the data specified in the instructions.

Household management station, located in the private sector, subject to the same requirements as production control stations. They must be installed in a dry and warm place that is convenient for maintenance. This may be a ground floor, a specially reserved room extension to the house or secure storage.

wall mount

In contrast to the large industrial cabinets, household models are compact and lightweight, so often they are available in wall-mounted

Connection should be carried out after full installed water system, Summed pressure conduit, cables are laid, assembled components, all carried out isolation of electrical elements. Connecting Shun, you should check out his work and in manual or automatic mode.

Technical support and service

Some of the production of control cabinets companies claim that maintenance is required. This is true, however, need regular inspection by the operator control unit. There is a periodicity set by the manufacturer, and for the proper operation of all the devices it is necessary to adhere to without fail.

Before inspecting or replacing any parts, disconnect the power and lock the equipment from reclosing. Independently, you can check for loose connections. The list of potential problems, as well as possible solutions, usually as indicated by the manufacturer.

Shun to order

Cupboard or downhole submersible pump control frequency converter for use in industrial boilers, utilities or private homes, made to order on individual TK

For example, a simple malfunction - not lit lights indicating the system is connected to an electrical cable. There are three reasons: there is no mains voltage broke circuit breaker or a blown bulb. Accordingly, the solution is to supply voltage, replacement of a switch or a lamp.
